Laminar Seal Rings A Smalley Laminar Seal Ring set is a metallic labyrinth seal consisting of multiple rings in a groove. The arrangement and the specific orientation of the rings are dictated by the application and the severity of the environment. There are 16 series of standard imperial and Metric Laminar Seal Ring configurations from which to select. 8 of these series are sets consisting of single-turn rings. The other 8 series are sets consisting of double-turn rings. Within each series are operational ring-set configurations in both imperial and metric sizes. The selection of the appropriate set should be determined by the application. For some applications a complete labyrinth configuration (i.e.; a complete labyrinth configuration is one which has rings staggered within the set) is necessary due to a severe environment where contamination is highly probable. In other applications design engineers can keep the groove dimensions minimal by specifying laminar sets with rings clinging either to the bore or to the shaft. Laminar Seal Rings Available From Stock Advantages of Laminar Seal Rings • No friction with other rotating components, ideal for high speed applications. • Prevent dirt and splash water from contaminating components. • When used in conjunction with other seals, Laminar Seals provide a primary seal against severe contamination, before the contaminants come in contact with the secondary seal. • Sets of multiple rings provide an efficient labyrinth seal. • Rings may be produced from a wide variety of alloys to withstand more severe conditions including higher temperatures and corrosive environments. • As a metallic mechanical seal they can outperform rubber seals in durability and life expectancy. • The change from rubber to metal reduces the need for frequent seal replacement. Standard parts from 5/8’’ to 50’’ and 15 mm to 1,300 mm. Special seals manufactured with No-Tooling-Charges. Smalley’s Laminar Seal Rings are interchangeable with FEY Rings.

The sets are comprised of single-turn rings in either 3 rings per set or 5 rings per set. APPLICATIONS: 3 ring sets protect components from low dirt and low splash water contamination. 5 ring sets provide a better labyrinth seal to protect components from medium dirt and medium splash water contamination. Double -Turn Laminar Seal Rings The sets are comprised of double-turn rings in either 2 rings per set or 3 rings per set. The double-turn rings fit tighter in the bore or on the shaft, provide complete 360° surface contact and resist higher axial/radial forces than single-turn ring sets, for medium to heavy duty applications. APPLICATIONS: 2 ring sets protect components from medium dirt and medium splash water contamination. 3 ring sets provide a better labyrinth seal to protect components from heavy dirt and heavy splash water contamination. 104 smalley.com No-Tooling-Charges™ For Customs Laminar Seal Ring Applications A. Coupling B. Bearing Protection C. Pulley Idler D. High Speed Spindle A.Coupling The seal arrangement in this assembly has been custom designed for optimum protection against contamination. Gases build up pressure in a center cavity, protected on both ends from contaminants entering. Manufactured in USA B. Bearing Protection The 3 ring set protects the ball bearing from contaminants like dirt and water. The seal retains grease/lubricant and prevents contaminates from penetrating into the critical components of the assembly. C. Pulley Idler The ring set designed in this application extends the life of the ball bearing by keeping contaminants from penetrating the precision bearing surfaces even though the bearing itself is sealed. When the shaft rotates only the groove ring rotates while the housing rings remain stationary. D.High Speed Spindle The QS series has been designed into the spindle assembly to protect the tandem bearings against corrosive elements. Though it is not the primary seal in the assembly, it is designed as the final seal protecting the bearings. All rings in the set will cling to the shaft due to the high rotational speed of the main spindle. Smalley (847) 719-5900 105 Laminar Seal Rings Single-Turn Rings Single-Turn Laminar Sealing Rings YH or YS are used for a wide variety of applications. They are commonly used to protect bearing systems by retaining grease/lubricant and preventing water or other contaminating liquids from penetrating into the critical areas of an assembly. The alternating (staggered) series YHK and YSK offer (due to an increased labyrinth seal) further improved sealing efficiency. They are often specified where the lubricating grease may liquefy due to higher operating temperatures or where protection against larger amounts of contaminating liquids (such as cooling water) is required.

They are suited for higher operating speeds, have 360° contact (no axial gap) and should be used where application conditions are more severe. One typical application is where high amounts of dirt and dust are present and the ring sets provide the necessary seal against contamination from outside elements. Double-Turn Laminar Ring Sets are also used to protect contacting radial seals, rubber seals, O-rings and other oil seals. For protection in the most severe environment the alternating (staggered) sets YHKD and YSKD are the preferred choice by engineers.
